Crawl Space and Basement Insulation in Montana

Foam board is best. Immune to mold and moisture damage, rigid foam insulation can be secured to foundation walls with adhesive or masonry fasteners.

Many houses have basement and crawl space foundations, but very few houses have foundation insulation. Instead of insulating foundation walls, most builders elect to install fiberglass batt insulation between the floor joists in the basement or crawl space.

Using fiberglass batt insulation anywhere in a basement or crawl space is not a wise choice. The batts can easily fall out of place from between joists. They do nothing to stop energy-wasting air leakage that brings outside air into the house. And the paper facing on fiberglass batt insulation provides a perfect place for mold to grow if there's moisture in the air.

Today, building scientists know that houses perform better when basement and crawlspace walls are air-sealed and insulated. These upgrades improve not just home energy efficiency but also building durability and indoor air quality.

Invest in a foundation transformation!

Whether your house has a crawl space, a basement or both, don't settle for damp, moldy space beneath your house. can transform basements and crawl spaces with a full range of improvements, from insulation and air sealing to waterproofing and Total Basement Finishing.

Basement air sealing and insulation

The first step in any basement or crawl space insulation upgrade is to seal the rim joist that extends around the perimeter of the foundation. Cracks in the rim joist, along with clearance holes (for plumbing and electric lines) cause major air leakage and energy loss.

Dr. Energy Saver can seal all these leaks with spray foam or a combination of rigid foam and spray foam, as shown in the photo at right.

After sealing the rim joist, energy technicians will insulate foundation walls with rigid foam insulation. The SilverGlo foam insulation boards used exclusively by Dr. Energy Saver outperform other brands of rigid foam insulation. They are faced with a radiant barrier that increases wintertime energy savings by reflecting heat back toward the living space.

Crawl Space Encapsulation

The problem:

Many crawl spaces still have dirt floors, foundation vents and uninsulated walls. Not surprisingly, these crude, unfinished spaces developed a reputation as dark, damp, moldy areas.

In an unfinished crawl space, moisture from the soil often causes mold to grow on wood and paper-faced fiberglass insulation, degrading both materials. Steel surfaces rust, damaging ductwork, water heaters and any other components beneath your living space. Insects and other pests settle in. Vents allow exterior air to move into the crawl space and enter the living space through floor openings (made for wiring, plumbing and ducts) and cracks.

The Solution:
Crawl space encapsulation solves all of the problems associated with dirt-floored, unfinished crawl spaces. Foundation walls are air-sealed and insulated to improve energy efficiency. A durable, moisture-proof membrane is installed over the dirt floor and extended up the walls to create a continuous moisture barrier. Drainage tiles and a sump pump can be installed if necessary to remove water from inside the foundation.

Foundation vents are sealed to keep pests and outside air from entering. Crawl space access is still possible through a tightly weatherstripped door.
